SPECIFICATION forming part of Letters Patent No. 236,732, dated January 18, 1881.

Application filed November 6, 1879.

To all whom it may concern Be it known that I. JOHN W. SUTTON, of the city, county, and State of New York, have invented certain new and useful Improvements in Rotary Pumps; and I do declare the following to be a clear, full, and exact description th ereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention is in relation to that class of rotary pumps which are composed of three essential partsa stationary case which incloses a rotating disk provided with swinging pistons.

My invention consists in forming grooves within the ends or sides of the disk and pistons, for the purpose of securing a waterpacked joint between the disk-pistons and the heads of the pump while in the act of pumping or measuring water; and, also, in so arranging the pistons with said disk that when closed on their seats their exterior surfaces will rotate in the same circle and in contact with but one point of the inner periphery of the 2 5 case. The grooves are an essential feature,

for without them there would be a great percentage of power lost, occasioned by the leakage between the heads of the case, rotating disk, and pistons; but by their use the fric- 0 tion resulting from ordinary metal or fibrous packing is avoided, consequently a greater and more economical result is derived from the power expended.

Figure l is a side elevation of the pump, Fig.

2 being an end view of the same. Fig. 3 is an elevation of the pump, with its end or head removed for the purpose of showing the disk and pistons. Fig. 4 represents a vertical section cutting through the case, disk, and pistons, in a plane corresponding with the movement of the disk. Fig. 5 is a sectional view, cutting the pump at right angles to the view shown in Fig. 4. Fig. 6 is a detached view of the disk with the pistons removed. Fig. 7

5 represents an edge view of Fig. 6. Fig. 8 represents the end of one of the detached pistons. Fig. 9 is an interior view of the same. Fig. 10 represents a broken section of the disk and one of the pistons. This view shows a spring projecting from a recess in the disk and pressing against the piston.

Like letters designate corresponding parts in all of the figures.

In Figs. 1 and 2, A represents the outer case of the pump, and B the removable head thereto. G is the induction to said pump, and D the eduction therefrom. E represents a journal-bearing for the purpose of supporting the journal projecting from one end of the rotating disk. F is a. journal-bearing upon the opposite end of the case. This bearing supports its opposite journal projecting from the said disk, which is driven by means of a belt passing around its pulley G.

In Fig. 3, H represents the rotating disk, which can be constructed of suitable metal or material, by casting or otherwise. The circumference of this disk is divided into three essential parts. TheiourpartsH are-all within the same circle and revolve in contact with one point of the circumference of the interior of the case M. 1? represents where four sectional segments are cut away forthe purpose of allowing the segmental pistons I 1 l l to fall within the circumference of the disk and form a part of the disk while rotating past the point of contact with the case. 0 represents four sockets or bearings formed within the disk at the terminus of the sectional segmental plane I. These sockets are made to inclose about three-fifths of a circle with the remaining two-fifths cut therefrom, thus leaving an opening, as shown in Fig. 6. One end of the segmental piston is provided with a journalbearing, J, which fits closely into said socket. The connection between said'bearing and segmental disk is made to fill about one-half of this opening leading from the socket o, for the purpose of allowing the pistons to swing outward and inward while rotating around in the case. f is a groove within the end of the piston, for the purpose of forming a water-packing between said piston I and the two opposite heads while passing around the waterspace between the disk and side of the case. k are grooves in the side or sides of the disk,

as shown in the figure, and in Fig. 5, L represents a depression within the two opposite sides of the disk.

Fig. 4 is a vertical section of my pump, cutting through on a plane indicated by the dotted line 00 w in Fig. 1. In this view the pistons are shown in position ready for raising and forcing water from the pump. 0 represents cavities within the piston, and d cavities within the disk corresponding to those in said piston. These cavities are for the purpose of receiving sand or dirt which may be in the water. Were the cavities not present to receive said sand or dirtthe disk would become clogged and stopped in consequence of the dirt getting between the two plane faces, thus enlarging the circumference of the circle when the segmental pistons come in contact with the inner periphery of the case. The bearing-surface of these pistons, as shown in the drawings, is very narrow; but I do not propose to limit myself to what is shown, for said edges can be reduced to a sharp edge and made to cut through small sticks or other like substances which may be drawn into the pump with the water.

6 represents a depression in the side of the case extending from the discharge to near the point of contact of the disk and pistons. This recess or depression is for the purpose of allowing the water between the case, disk, and closing piston to escape after said pistons have passed the eduction-port. Thus less power is required to operate the pump than would be required were this feature not employed.

Fig. 5 represents a vertical section cutting through on the plane indicated by the dotted lines y y, as seen in Fig. 2. In this View A represents the case; B, the removable head thereof. H is the rotating disk. I are pistons with grooves ftherein. k and I represent water-packing grooves within the two opposite sides of the disk. E is an annular journal,

with grooves 'i therein for water-packin g.

Fig. 6 is a representation of a plan view of the rotating disk with the pistons removed, H being four segments within the same circle. P represents four plane surfaces, which form seats for the segmental pistons. (Shown in detached views 8 and 9.) 0 are the sockets in which the rocking journals J rotate.

Fig. 7 is a side view of the disk, showing the segments of the circle H, plane faces 1?, recesses d, and sockets 0.

Fig. 8 represents an edge view of one of the pistons, while Fig. 9 represents an internal plan view of the same.

In the broken sectional view, Fig. 10, H is the disk, with sockets g therein. These sockets are for the purpose of receiving the springs h, which project therefrom and come in contact with the interior of the piston, for the purpose of throwing said piston out against the walls of the case when the centrifugal action is not sufficient, or when the position of the pump will not admit of said pistons being thrown out as aforesaid.

I am aware that rotary pumps have been constructed with swinging pistons attached to a rotating disk. To this feature I lay no claim; but

.What I do claim, and desire to secure by Letters Patent, is

1. In combination with the case of a rotary pump, the inner periphery of which is a true circle, having a rotating disk provided with abutments rotating to one side of the center of said case and in contact with the inner periphery thereof, the swinging pistons, the exterior of which, when closed, complete, with said abutments, the circular form of said rotatin g disk, which revolves in contact with said inner periphery, as described, and for the purpose set forth.

2. I11 combination with the case of arotary pump, the inner periphery of which is circular in form, a rotating disk provided with swinging pistons with recesses therein, channels or grooves in their edges and the faces of the disk, for the purpose of forminga Water-packed joint between their sides and the interior surfaces of the case of the pump.
